  7. WA to introduce new drug and drink driving penalties | 1 July 2021
28 Jun 2021

Naomi Sherrington, Senior Lawyer and Julia McCullagh, Lawyer in our Crime and Traffic and Dispute Resolution teams outline what penalties you could face if you are a driver or rider and are caught with drugs in your system and/or are over the legal alcohol limit.

As of 1 July 2021, the State Government’s new Road Traffic Amendment (Impaired Driving and Penalties) Act 2019 is coming into effect.

What is a polydrug offence?

As of 1 July 2021, the State Government is creating a new “polydrug” offence. Currently, similar penalties apply for driving under the influence of alcohol alone, drugs alone, or alcohol and drugs in combination.  The new law separates the offence of driving under the influence of alcohol or drugs from the offence of driving under the influence of both.  Under the new “polydrug” offence a person commits an offence if they drive or attempt to drive with a   blood alcohol content of above 0.05 while also under the influence of drugs.  The penalties for these new “polydrug” offences will be higher (generally 1.5 times more) than the penalty for simple drink driving.

What is drug driving?

A person who drives or attempts to drive a motor vehicle while under the influence of drugs to such an extent as to be incapable of having proper control of the vehicle commits an offence.

The legislation differentiates between a driver who has certain listed illicit drugs present in their system and driving while impaired by drugs generally. 

If a person is found to be driving with certain illicit drugs in their system, there is no need for the prosecution to demonstrate that they were “incapable of having proper control of the vehicle” or a similar element. It is sufficient that the illicit drug or drugs were detected. Currently, the list of illicit drugs for this offence are, tetrahydrocannabinol (THC/cannabis), methylamphetamine and MDMA. It is not clear if the state government will be updating this list when the new road traffic legislation comes into effect on 1 July 2021. 

The offence of driving while impaired by drugs has a much broader definition of “drugs” and includes lawful prescription medication. To be convicted of this type of offence a person must have driven a vehicle with one or more drugs present in their system to the extent that they were incapable of having proper control of the vehicle: or

  • the conduct of the driver was consistent with a person who has consumed or used that drug or those drugs; and 
  • the conduct of the driver was inconsistent with the person being capable of having proper control of a vehicle.

It is a defence to this type of offence if the drug was administered by a medical practitioner or nurse and the person charged could not reasonably have been expected to be aware that the drug was likely to affect their driving. In these circumstances, it may be relevant if the packaging did not include a label advising that the drug would effect driving.

What about medicinal cannabis?

In WA, it is an offence for a person to drive with THC present in their system, regardless of whether the THC comes from prescribed medicinal cannabis.  A person with a blood alcohol content of above 0.05 and THC present in their system because of medical cannabis use will still be captured under the polydrug offence with its higher penalties. 

What else is changing?

Certain other changes to the law are also coming into effect as of 1 July 2021, this includes allowing a police officer to immediately prohibit a driver who tests positive to the presence of THC, methylamphetamine and MDMA at the roadside from driving for the next 24 hours  (this is in addition to any other penalties that they might face).

What are the new drink driving penalties?

The new legislation is also increasing the penalties for drink driving, key new penalties are as follows-

For driving with a blood alcohol content of or above 0.05  but below 0.08 for a first offence a person is liable for a fine of up to $1250.  Penalties for second or subsequent offences against this section are set out in the below table.

"Always fast and thorough service. Thank you"

Sitka Pil

My circumstances at the time I made contact with HHG were dire following my argument being rejected by two no win no fee firms. Following my initial meeting with HHG's employment law team I was left feeling extremely positive by the response and concern shown by HHG in regards to their support of my argument along with their preparedness to pursue an outcome on my behalf.

I accept the fact that nobody really wins in these cases (mental health/ workplace) however the end result was what would be considered most favourable and far in excess of what would have been achieved had I not sought the advice from HHG.

I have no hesitation in recommending HHG to anyone caught up in the messy circumstances I found myself in at the time.

Great advice and five-star commitment to their client!!"

Nathan Lynch

"Thank you for such great assistance with the transaction of Flying Domestics on behalf of Lorna Good. It has been such a pleasure to work with the HHG Legal Group and I look forward to working with you in the future."

Although I hope not to need their services again in future, I would be confident in doing so!"

Dr Lana Bell

"A good outcome is what we can expect.  A great outcome is a sign of a company which does the very best for their clients. A very big thank you to Daniel Morris for showing empathy towards my small and much needed legal action.
